    Hardware Diagnosing broken wifi with working Bluetooth

    Hey all I’ve been facing a weird issue with a switch lite I have picked up. I’ve heard that the cyw4356x chip can fail quite often but when I test for shorts I only see a few grounds coming out of the chip which very well could correctly be ground? See image below with circles around ground...

    Tips and tricks for resoldering GPU 1uf 0201 caps?

    It depends how many coffees I am down for steadiness haha! Iron would be the better choice because it lowers risk to the GPU solder, but I have low confidence in the quality of the joint I will get with my tips and skill vs hot air. I’m pretty sure it would be fine without the cap but I do feel...

    Tips and tricks for resoldering GPU 1uf 0201 caps?

    Cheers I’ll see if my local has solder paste or I’ll just yolo it and pre tin with regular rosin core solder Edit: they do! However they only have a single type which is the SN63PB37 which I worry could require too much heat and result in me melting some GPU solder balls. Are there any types of...

    Tips and tricks for resoldering GPU 1uf 0201 caps?

    Hi! After undoing a mod during diagnostics for a faulty switch I ripped off and lost one of the 1uf 0201 ceramic caps from the GPU (the left most one) I was able to find a post on here to get what cap I need and even instructions to use a hot air rework to resolder the smd cap. I was wondering...

    Hacking Flex cable for RP2040 OR board with inbuilt resistors?

    Oh wow if that’s actually the case that is mad. When I look into the item on its web page it says based off of the RP 2040 but doesn’t mention anything about what is actually different. I can see what looks to be like resistors on the board but is there anywhere I can read into this chip in...

    Hacking Flex cable for RP2040 OR board with inbuilt resistors?

    Hey! Just putting the finishing touches on my first picofly and overall the only real pia experienced in the process was the resistors on the RP2040. The resistors just didn’t like my 38awg wire being soldered to it and it was super annoying when occasionally I would desolder the other end of...
